In a brief BMJ article, George Davey Smith describes Nazi Germany's pioneering campaigns against smoking, drinking, overeating, and other unhealthy habits. (Robert N. Proctor's 1999 book The Nazi War on Cancer explores this topic in more detail.) "It may seem paradoxical that the robust identification of one of the most important environmental causes of disease of the 20th century occurred in a totalitarian state," Smith writes, referring to Nazi research on the link between smoking and lung cancer.

Uh, no it doesn't seem paradoxical at all that totalitarians would try to micro-manage individual decision-making.
